National Ambient Air Quality Status - 1999

                                             
                                              Foreword


The Central Pollution Control Board (CPCB) in collaboration with the State Pollution Control Boards (SPCBs) has established a National Ambient Air Quality Monitoring (NAMP) network, comprising 290 stations in 92 cities/towns, under the Air (Prevention and Control of pollution) Act, 1981 to collect, compile and disseminate information on air quality.

The Ambient air quality is monitored by CPCB, SPCBs, Pollution Control Committees, some Universities and Institutes. The data, thus generated, are transmitted to CPCB for scrutinization, analysis, compilation and publications as a consolidated report.

This report contains ambient air quality data for the year 1999. Air pollution status of various pollutants has been defined in terms of Low, Moderate, High and Critical, vis-à-vis the notified ambient air standards and has been depicted in the form of tables and maps. The co-operation of the monitoring agencies is gratefully acknowledged.
